T 0 all whom it may concern:

Be it known that I, NOAH L. NINE, a citizen of the United States, residing, at P010, in the county of Ogle and State of Illinois, have invented certain new and useful l1nprovements in Pole-Changers, of which the iollowing is a specification.

My invention relates to improvements in that class oi electrical devices lcnown as polechangers and the objects of my invention are,

first to provide a. device for continuously receiving therein a direct constant current and for producing successive alternating currents along a selected line; and second to provide means for producing a series of pulsating direct currents of positive and negative polarity respectively from the same source of electricity and simultaneously with the production of the alternating current.

My invention further resides in the pro vision of a device in which the alternation takes place when the current enters the device, rather than when delivered therefrom as in ordinary types.

My invention further resides in the provision of a device in which the pulsating currents are led directly from the source oi electricity, through ringing circuits, through a common return brush and back again, thus using but one set of contacts for all ti e currents.

My invention l'urthcr resides specifically in the following features of construction, arrangement and operation as will be hereinalter described with reference to the accompanying drawings, in which like numerals are used to designate like parts in the several figures, and in which Figure l is a plan view of my improved ap- )aratus, Fig. 2 is a transverse section on the line ot Fig. 1, and Fig. 3 is a vertical longitudinal sectional view thcrcthrough.

1n the practical embodiment of my invcntion i provide a cylinder i of insulating material arranged to be constantly revolved by means of a rotatable shalt 2 upon which it is mounted. The shaft 2 may be arranged in suitable bearings 23 mounted upon a base plate A as desired, although said mounting is in no way tributary to this invention.

The cylinder 1 is provided with two spaced rings 4 and 5, ol' brass or other conducting material, embedded therein and extending completely thercaround. Said cylinder 1 is 'lLllLlCl provided with a pair oi segments 6 and cmhcddcd within and exc uding upon through l l I i l i i i i l i i l i l he same plane partiall around said cylinder 0 iorrn a conductive mud on the opposite sides of said cylinder with insulated portions lying between their ends on opposite sides of said cylinder parallel with the axis thereof. The commutator ring l is connected to the segment 6 by means of a concealed conductor 7 extending therehctween below the surface of the cylinder 1 upon one side of the cylinder, while the con'imutator ring is connected with the segment 8 by means of a similarly formed concealed conductor 8 within said cylinder from the opposite side thereof. Brushes 9 and 10 are arranged to contact with the complete commutator rings l and 5 respectively upon the same side, while brushes ii and 12 are arranged to contact successively with the segments 6 and 7 upon opposite sides of the cylinder 1.

A. direct constant current is led from the battery 13 through positive and negative conductors 14 and 1:) to the brushes 1]. and 12 respectively, a supplemental circuit 16 extending from the brush l1, being conveniently grounded at 17, and forming telephone circuit for the action of the positive pulsating current. In like manner a conductor 18 is led from the opposite brush l2 and is grounded at H) forming a telephone circuitl'or the action of the negative pulsating currents. Conductors 20 and 31 leading from the brushes t and ll) 1'CSl) ,lil\'()l are mounted at 22 and 23 respectively, conductor iorming a common return for the positive and negative pulsating currents, the conductor 21 forming a telephone circuit to receive, and for the action of, the alternating currents.

In operation, current is led from the battcry 13 through the ositive conductor 14 into the brush 11, it being understood that the shalt 2 and cylinder 1 are constantly rotated by any suitable means. From the brush 11 the current llows into the commutation segment 6 in the position shown in Fig. i; from segment (5 to ring by the concealed conductor 7; from ring 4 through brush 9, conductor ill to the ground at through the ground to the telephone circuit 21, through brush 10, ring 5, through concealed conductor 8 and through the conductor 15 hack to the battery 13. Upon ahall revolution of the cylinder 1 however, the current will flow from battery 13 through the conductor 14, brush 11, com- Inutatimr segment 8, ring 5, brush 10, down the telephone circuit 23, to the to segment ground at 23, through the ground to con uctor 20, to brush 9, ring" 4-, segment 6, rush 12 and conductor 15 back to the batcry; thus it will be seen that when cylinder 5 l is in the position shown in Fig. 1 the current passes up through the telephone circuit 21 While when said cylinder has revolved one half revolution the current passes down through said telephone circuit 21 as de- 0 scribed, and by wliiclnmeans the alternation is efiected, it being further seen however, that the alternation takes place as the current enters the cylinder 1, depending upon the position of the segments 6 and 8, rather than when the current leaves the cylinder as 111 pther devices.

it will be further seen that simultaneous with the production of alternating currents I am able to obtain pulsating currents, that is currents which are successively intermit-v tently produced to actuate a telephone bell or the like, Wound to respond only to intermittent currents of a )ositive or negative linder l is in the posltion shown in Fig. 1 the current will flow polarity. i /hen the cy -ncealed conductor 7, brush 3a in the telephone circuit thereof.

brush it and back through condu through the conductor 15 through the telephone circuit 18 to the ground at 19 through e ground to the return conductor through brush 9, ring 4, segment 6, through I igh conductor 14; this circuit as deed being completed each and every time segment 6 contacts with the brush 13., and 5* runs a negative pulsating current with-- I this current as described being formed each and every time the segment 6 contacts with I the brush 1 2 and forming a positive pulsating I current Within the telephone circuit L Having thus fully described my invention, I claim:

In a pole changer for transforming direct constant currents into alternating currents and pulsating currents of positive and negative polarity, the combination of a constantly rotating cylinder of insulating mate- F rial having pair of spaced commutation I rings extending continuously therearound and a pair of commutation segments extending partially therearound in the same plane and leaving portions of said insulated cylinder between the adjacent ends thereof, each of said segments having connection through i y l rings, brushes mounted to contact upon the surface of said rings and segments, a battery having conductors leading to each of said segment brushes, grounded conductors leading from each of said ring brushes, one of said grounded conductors constituting a telephone circuit adapted to-receive the current alternately in different directions ther from said segment brushes, and constituting telephone circuits adapted to r ceive direct pulsating positive and direct pulsating negative currents respectively having a common return through the other of said ring brush conductors, substantially as described.

I In testimony whereof I my signature in presence of two WibIlfiS"S.
